MOTOR BRACKET.

Application filed May 8, 1926. Seri'al No. 107,727.

This invention relates to improvements in motor brackets, particularly adapted for attachment to sewing machine heads to secure electric motors thereto for hand wheel driv-.

with respect to the machine hand wheel.

A furtheirobject of the invention is to provide a vertically adjustable motor carrying bracket which may be locked or clamped in any adjusted position.

A further object of the invention is to provide an adjustable motor bracket of the class described adapted for mounting on the side portieri of a sewing machine head.

A further object of th-e invention is to provide a motor bracket of the class described which is of very simple construction, is easily manipulated, is strong and durable, and is well adapted `for 'the purpose described.

lVith the above and other objects in view the invention consists `of the improved motor bracket and its parts and combinations as set forth .in the claims and all equivalents thereof.

ln the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is an end view of a sewing machine head having secured thereto the improved motor bracket holding a motor in adjusted relation with respect to the hand wheel;

Fig. 2 is a. side view thereof; and

Fig. 3 is a sectional view taken on line 3 3 of Fig. 2.

Referring now more particularly to the drawing it will be seen that the numeral 5 indicates a sewing machine head having revolubly mounted at its end a hand wheel 6.

The side portion of the head has cast and milled thereon in vertical alinement,'a. pair of flattened projecting portions 7. Adapted to be slidably secured against said portions is a bracket or plate member S which, at its upper side portions is formed with outwardly olf-set portions 9 to engage the inner face of an electric motor 10, 'the motor being held thereto by screws 11.

Formed in the medial upper portion of the plate member S is a vertical slot 12, en-

larged and rounded at 13 and below the slot 12 is an elongated slot 14:.

The plate member 8 is secured against the upper shoulder 7 by means of a threaded stud 15 which extends through the slot 12 and is threaded into the head member. Said stud is formed with a pair of spaced apart head or enlarged portions 16 and 17, one on each side of the plate member and the outer portion 17 is suiiiciently small to permit its passage through the enlarged portion 13 of the slot y12.

The plate member 8 is also held against the lower shoulder portion 7 by means of a threaded stud 1S, threaded into the head and extending' outwardly through the slot 11- in said plate member. Said stud has an integral head portion 19 adapted to engage the inner face of the plate member. A cap member 20 is threaded onto the outer end portion of said stud.

By reason of the arrangement described when the cap member 20 is unthreaded the plate member is free to be moved vertically on the studs 15 and 18 accommodated by the slots 12 and 1'1-. In the normal position shown in the drawing the bracket is so adj usted that the pulley wheel Q1 of the motor will be in close contact: with the rim of the hand wheel to drive the same and the bracket is held in adjusted position by tightening the cap member 20 which clamps the plate member unmovably between the lstud portion 19 and the cap. Obviously, the bracket may be lowered to position wherein the pulley wheel is disengaged from the hand wheel. In this position bobbins may be readily wound. Also, it is possible to entirely remove the bracket from the head by lowering it to its lowermost position and removing the cap 20 from its stud. The plate may then be removed from both studs as the portion 17 of the upper stud will pass through the slot enlargement 13.

From the foregoing description it will be seen that the improved motor bracket is of very simple and novel construction, and is well adapted for the purpose set forth.

lVhat is claimed as the invention is:

1. rThe combination with a sewing machine head having a hand wheel, of a plate member formed with a pair of slots, one of said slots having an enlarged portion, studs extending from the head through the slots of said plate member, one of said studs having a head, the plate member being movable vertically with respect to said studs, a motor carried by said plate member removably engaging one et the studs and the plate to clamp the latter in an immovable adjusted position, the removal of the cap member permitting a movement of the plate whereby the headed stud may pass through the enlarged portion of said slot to effect the entire removal of the plate.

2. The combination With a sewing machine head formed with a pair of shouldered portions on the side thereof, of a hand Wheel,

a slotted vertically positioned pla-te member, studs extending from said shouldered p0rtions through the slots of said plate member, the plate member being removable from said studs and also being movable vertically with respect thereto, a motor carried by said plate member for driving said hand Wheel, and a cap member engaging one Vof the studs and the plate member to clamp the latter in an immovable adjusted position.
